To all whom it may concern:

lBe it known that I, ()soAR FALKENWALDE, a citizen of the United States, residing in the city of Baltimore and State of Maryland, have invented certain new and useful Improvements in Water-Gas Burners; and I do hereby 'declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it 'appertains to make and use the same.

The invention relates to a Water gas burner.

The object of the present invention is to improve the construction of hydrocarbon burners and to provide a simple, practical andeflicient water gas burner of strong, durable' and inexpensive construction designed for use in furnaces and various other places and equipped with means for simultaneously vaporizing oil and water and causing a commingling of the same and discharging.

the mixture in a plurality of jets whereby the burnerwill develop intense heat 'at the minimum cost.

A further object of the invention is to provide a burner of this character adapted to be easily primed and readily started and equipped with an automatic valve for controlling the inlet of the water to feed the same as required and prevent a flooding or excess of water when a gravity or other pressure feed is employed.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details; of construction, within the scope of the claims, may be resorted to without departing from the'spirit or sacrificing I any of the advantages of the invention.

responding parts in the several figures of the drawings.

In the accompanying drawings in which is illustrated thepreferred embodiment of the invention, the water gas burner comprises in its construction a base 1 construct ed of suitable metal and preferably concavoconvex and provided with a marginal flange 2 curved upwardly and forming a peripheral groove and constituting the outer Wall of the groove. The base is circular in plan View and its upper face may be provided with a lining 3 of more refractory material than the body of the base, which is adapted to operate as a combined starting cup and refleeting element. The upper face of the base is convex and presents aninclined surface and the oil which is adapted to drop upon the base in the starting of the device will run down the sides or inclined faces of the base and collect in the marginalgroove or gutter if the supply should be more or less excessive. This will prevent any of the oil from being wasted and will insure a burning of all of the oil used in starting the burner.

The base is provided with a central opening 4: in which is secured a water conduit 5 illustrated in the accompanying drawings as consisting of a plurality of pipe fittings and couplings and receiving an inner oil Will Eli

conduit 6 extending upwardly through the outer Water conduit and forming an intervenlng water space or passage between it and the water conduit. A coupling 7 is connected with the lower end of the oil conduit seat 12. The base is firmly clamped between the reducing nipple l1 and the lock nut 10, a spacin sleeve 13 being interposed between the lock nut and the lower face of the base, as clearly illustrated in Fig. 2 of the drawings.

The valve seat 12, which is beveled, is formed by the upper end of the reducing lltltl Illli film nipple and the pipe section 14;, and a valve 15, which is slidable on and guided-by the upper portion of the oil pipe 6, coacts with the valve seat. The lower end 16 of the Valve is beveled to fit the valve seat and the said valve is composed of upper and lower sections, the upper section 17 being in the form of a reducin nipple and having an inner lining or pac ing 18 adapted to form a practically water-tight connection between the valve and the upper guiding portion of the oil tube. The valve is maintained closed by gravity and the internal pressure of a drum 19 consisting of a casting and having a lower threaded opening 20 for the reception of the reducing nipple 11 of the water conduit. The drum 19, which is divided by a horizontal plate or portion 22'into upper and. lower chambers or compartments 21 and 22, has an upper threaded opening 23 intowhich is screwed a tubular portion 24 of a hollow superimposed spider or casing 25 and the said oil tube extends into the spider and has its upper end arranged in spaced relation with the inner face of the tubular portion 24 to provide an intervening space for the passage of the water or oil va ors. the partition 22 is provided .wit a central opening 26 of slightly greater diameter than the exterior of the oil tube to provide a central annular passage.

The drum is also provided with a series of vertical tubes 27 formed integral with the drum and extending from the top to the bottom thereof and providing vertical passages 28, which extends entirely through the drum and into which is discharged the mixture from the spider 25. The horizontal partition plate 22 terminates at the tubes and its periphery is spaced from the interior of the drum 19 to provide an outer opening or space 26 which communicates w th the upper and lower compartments of the drum. The drum is shown provided with five vertical passages 28 and the spider consists of a central portion and five radially arranged arms 29 having depending nipples 30 provided with jet apertures 31 for discharging the combined oil and Water gas into the vertical passages of the drum. The arms are provided with longitudinal openings 32 and are closed by removable lugs 33, when the passages 32-are drilled. t is not necessary to clean the hollow spider or superimposed casing, as the water gas is not burned at the nipples and carbon will not collect in the passages of the spider of easing. Also the water gas passing through the same will maintain the passages of the spider in a clean condition and the spider will also operate to dry and heat thecommingled vapors; The nipples 30, which are squared at their outer portions to receive a wrench, have threaded inner or upper portions 34 which are screwed into threaded openings maintains the latter in a'closed spider. The mixture is discharged downwardly from the jet apertures and it has been found by experience that it burns with an'intense green flame. The drum becomes 35 in the lowerwalls of the arms of the I enveloped in such flame. and air to-support The base is preferably enlarged as shown around the openings and the air tubes, which become highlyheated, extend abovethe plane of the bottom of the drum.

The spider forms a convenient priming device as the oil, when the full flow is turned on, will be discharged from a tip or head 39 having openings 40 located op osite the passages of the arms ofthe spi er. The oil will then drip or flow from the nipples and will be discharged upon the plate or base. The oil on the base is then ignited and the burner started. After the burner is started the-flow of oil is cut down and instead of discharging into the passa es of the spider and jet it will ooze or' ischarge slowly from the openings 40 and flow' down the oil pipe or' tube exteriorly of the same into the drum and will mix or float upon the water contained therein and the heating of the drum will cause the boiling of the liquid contents thereof and a vaporization of both i the oil and water, the horizontal plate or partition operating as a heating element to assist in va orizing the oil and water. The commingle va ors or gases resulting from the boiling of t e oil and Water will under the pressure created in the drum by the heating of the contents thereof pass upward and enter the superimposed casing or spider and discharge at the nipples thereof. The gas discharged from the nipples burns at the lower portion of the drum where it mixes with the hot air from the air tubes 36, producing an intense heat which may be varied by controlling the flow of oil to the burner. It has been found in practice that the pressure within the drum acting on the. valve osition during a portion of the time and W on the pressure is decreased through the consumption of the gas the valve will open under the pressure of the water and permit a uantity of water to enter the drum. en the burner is running steadily the valve opens and shuts in comparatively rapid succession. Also in practice suitable valves (not shown) will be employed for controlling the flow of water and oil to the'burner. The superimposed hollow spider or casing may consist of a casting or be constructed in any other desired manner and the threaded portion or neck 24, which is screwed into the top of the drum is locked to the same by a masses lock nut 41. Suitable gaskets or packings may be employed where required to produce a steamtight or water-tight joint or connection.
